Supervised vs. Unsupervised Learning: What's the Difference?

TLDRSupervised learning uses labeled input and output data, while unsupervised learning doesn't. Supervised learning can be further divided into classification and regression, while unsupervised learning includes clustering, association, and dimensional reduction. Supervised learning requires human intervention for labeling data, while unsupervised learning discovers patterns without labels. Though supervised learning is more accurate, unsupervised learning is useful for unlabeled data and finding hidden patterns. Semi-supervised learning is a middle ground using both labeled and unlabeled data.
